说明 |
GIF只限于8位调色板,总共256颜色。GIF格式因此非常适合保存有较少几个颜色的图形,例如简单的图表,形状,标志,漫画式图像等。GIF格式支持动画,至今仍广被用来提供图像动画效果。它使用的无损压缩,同样颜色的面积越大,效果也强。不过图像太过详细或有抖动的话就不管用了。 |
High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. It was developed by the Moving Picture Experts Group. |
